AUXILIARY SHIFTING GUIDE FOR Application. filed May 6,

1 '0 all whom it may concern:

Be it known that we, JOSEPH W 001) and lVAL'rnn I'IAYNES, citizens of the United. States, and subjects of Great Britain, re-. spectively, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in an Auxiliary'Shifting Guide for Spinning and Roving 'Machines, of which the following is a specification.

Our invention. relates to a new and useful improvement in auxiliary shifting guides for spinning and roving machines, and has for-its object to so construct and. place a series of the guidin mechanism rel.- ative to a spinning or roving machine that it will insure the properamount' of transverse movement to the strand of yarn or thread in its feed to the leather. covered drawing rolls, thus preventing the cutting. of the leather covering of said rolls and therefore preventing the occurrence of flaws in the strands or threads which has'heretofore been a serious drawback to such malVith these and other ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, We will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this application, in which:- 1

Fig. 1 is a side elevation of a portion of a spinning machine showing our improvement applied thereto.

Fig. 2 is a plan view of Fig. 1, the outer bar of the shifting frame being included. i

Fig. 3 is a detail side view of one of the side bars of the shifting frame.

Fig. at is an enlarged plan view of one of a number of specially constructed combined bearing and guide bracket.

Fig. 5 is an edge elevation of Fig. 4.

Fig. 6 is a rear view of Fig. 5.

Fig. 7 shows a strand of yarn or fibrous material as it is produced upon a spinning machine having this improvement embodied therein.

with the roll 3 for guiding the yarn or other fibrous material from the supply spool or bobbin, 4 and 5 are the guide or supporting rolls over which the strandof yarn 6 passes and these last named rolls are mounted in open bearings in the brackets 7 which brackets mounted upon the frame and held in any adjustment by the bolts 8 and such ama chine isalso provided with a series of standards 9 in which are journalled the leather covered drawing rolls .10 which coact with a feed roll 2 coa'cts the fluted rolls 11 for drawing or elongating.

are adjustably 2 12 represents our combined bearing and guide brackets one of which is adjustably attached to certain ofthe standards 9.in order that a guide roll 5 may be j ournalled in these brackets in close proximity to the drawing roll 10; and 13 represents the open bearing'in each of the brackets for the re ception of the shaft 'of the roll 5.

Formed with and projecting from the bracket 12 is a guide member 14 in which is formed the slot 15 for the reception of the:

transverse shifting bar 16 and this bar guides 17 each having a suitable hole therein for the passage of the strand 6 on its way to the rolls 10 and ll. The shifting bar 16 has annular extensions 18 by means of which it is secured to the side bars 19 of the shifting frame and said side bars having upturned slotted ends 2G for the reception of the bolt 21 for securing the parts together. g

The side bars 19 are connected with the angular extensions 22 of the shifting bar 23'which is provided in machines of this type, this last named shifting bar. also carrymg the guides 24 having the usual holes therethrough for the passage of the strands or threads 6. The bars 19 of the shifting frame are slotted as indicated at 25 so that the bolts 26 passing through suitable holes in the extensions 22 and said slot will secure the shifting bar 23 to the frame .19 in such manner that the shifting bar 23 may be adjusted to accomodate the adjustment of the rolls 2 and 3 and the rolls 5 for spin ning material of various lengths of fibre. The usual mechanism for reciprocating the shifting bar 23 is utilized for reciprocating the shifting bar 16 since these bars are coupled up as before described by the side bars 19. This reciprocation of the shifting bars 16 and 23 and. cons quent y the g id an Lil dency to cut or weargrooves'in the leather cover. 1 I

Heretofore this lateral shifting of the threads has been effected by guides placed at a considerable distance from the rolls 10 and ll'so that the t-hreads werepresented at such'a slight angle to the rolls as to make the lateral shifting of said threads uncer "tain'with the result that the leather coveringsof the rolls 10 in 'asliorttiine were'cut or grooved but we have entirely overcome this ditliculty by'so constri'ictingthe combined bracket 12 thatit may be bolted directly against the standards 9 and as these brackets carry the guide members l4: the reciprocating bar 16 and the guides 17 'carriedthereby are brought in close proximity to the rolls 10 and 11 thusinsuring a posi-" tive even lateral shifting of the threads .6 between these rolls. This construction and arrangement also leaves the standards 7,

rolls-2 and 3 'andshift-ingbar 23 independent for adjustment 'to accomodate for the spinning of material of different length fibre. By actual practice we have demonstrated that the producing of flawy work is entirely overcome by the use of our improvement and that perfect threads are spun such as represented in Fig. 7.

Of course we do not Wish to'be limited :to the exact'details of construction as herein shown as these may be Varied within the limits of'the appended claims without departing from the spirit of our invention.

Having thus fully described our-inventionfwhat we claim as new and useful is 1. In a machine of the character described in combination ,withwthe bearing standards ofthe drawing roll, combined bearing and guide brackets secured to said standards, a guiding roll journalled in the brackets, a laterally reciprocating bar mounted upon said'brackets, and a series of thread guides mounted upon said barf 2. In a spinning machine having bearing; standards for drawing rolls,-a series of combined bearing and guide brackets secured to said standards guide rolljournalled in said brackets, a reciprocating bar also mounted in-said brackets, and a series of thread guides carried by said bar, said guides projecting in close proximity to the drawing rolls and having holes therea through for the passage of the threads being spun.

In testimony whereof, we have hereunto afiiXed our signatures. I JOSEPH VOOD.
